Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a refrigerating device such as a refrigerated showcase or a topping case used for displaying toppings at a sushi restaurant, etc. [Technology] As is well known, such a refrigeration device has a machine room that houses a compressor, etc., and a display room that houses a cooling vibrator, etc., and expands the refrigerant sent from the compressor and passes it through the cooling pipe. ,
It is used to cool, display and preserve, for example, sushi toppings in a display room, and various structures have been proposed and used in the past.

However, in either structure, for example,
As shown in Publication No. 37666, the bottom plate of the display room was almost horizontal. [Problem to be solved by the invention] Therefore, even if the display room is provided with a drain, when the display room is washed with water, the water will not drain well, and the washing water will drain to the bottom plate part far from the drain. There was even a fear that water droplets tend to remain, and if frequent cleaning is neglected, small impurities may accumulate on the bottom plate and re-adhere to the items on display, that is, the toppings.

Therefore, the purpose of the present invention is to improve water drainage after washing, etc.
The object of the present invention is to provide a refrigeration device that can eliminate the above-mentioned drawbacks. [Means for Solving the Problem] In order to achieve this object, the present invention provides a refrigeration device including a display chamber having a bottom plate on which a display stand is placed.
The bottom plate has a concave groove extending in the longitudinal direction of the refrigeration device in the middle of extending downwardly from the rear side of the display room toward the front side, and a drain port communicating with the outside is formed in the groove. It is characterized by the fact that In a preferred embodiment, a bottom plate is fitted into the concave groove portion of the bottom plate so as to be substantially flush with the top surface of the remaining portion of the bottom plate. [Function] Since the concave extinguishing section is formed on the inclined bottom plate, the cleaning water flows smoothly on the bottom plate, enters the lecture section, and is discharged to the outside from the drainage port formed in the extinguishing section.

When the refrigerator is in use, the drain port is closed with a lid to prevent cold air from escaping from the display room.

If the lid is closed, water can be stored in the groove.

[Embodiment] Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, in which the same reference numerals indicate the same or corresponding parts. In addition, although the present invention will be described below with reference to a case where it is applied to a topping case used in a sushi restaurant, etc., as is clear to those skilled in the art, it can also be used to store or display items other than sushi toppings. It is not limited to neta cases. FIG. 1 shows an outline of a neta case (refrigeration device) 1 according to the present invention. A side force bar 4 is attached to the top force bar 34, which fits into the top force bar 34. Therefore, almost the entire length between both ends of the neta case 1 is the display room 2. When this topping case 1 is placed on a counter (not shown) in a sushi restaurant, the front side in FIG. 1 is placed facing the customer, and the back side shown in FIG.
